Device for converting motion



NITED STATES PATENT LEFIGEO DEVICE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 278,899, dated June 5, 1883.

Application filed April 26, 1883. (No model.)

To all whom it may concern Be it known that we, ALEXANDER ELSON and FINLEY M. QnooKErr, citizens of the United States of America, residing at Union ville, in the county of Putnam and State of Missouri,- have invented certain new and useful Improvements in Converting Motion; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it zip-pertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of reference marked thereon, which forms a part of this specification.

The object of this invention is to provide an improved apparatus for converting motion,

whereby the reciprocating motion may be changed into a rotary 5 and it consists in an apparatus having a driving-wheel with a transverse shaft, upon-which is located a ratchet-wheel which is provided with side flanges, with which ratchet wheel engage, above and below the same, separate ratchet-bars, which are pivoted to each other and to a vertically-slotted arm, said ratchet-bars being united at their ends by a suitable spring, and the arm being connected to the shaft of a vertical pendulum, which is weighted at each end and provided with means for reciprocating the same, as will be hereinafter more fully set forth and described.

In the annexed drawing we have illustrated our invention by a perspective view, in which- A represents a suitable frame, which supports the operating mechanism, and is provided with transverse and longitudinal beams, as shown. To the upper part of this frame is secured a cross-bar, B, which is .provided near its cenfor with a downwardly-prqjecting arm, and at one end of the same with a pendulum-lever, which is firmly secured to the cross-bar B. This lever is provided at its ends with weights, as shown, the upper weight being of less size and gravity than the lower one. To the lower weight, near the base of the same, is attached a rod which connects with a lever, D, which is pivoted to the frame; By means of this 1ever areciprocating motion is given to the pendulum C. To the downwardly-pro eeting arm E of the cross-bar B are pivoted two ratchet- 5o bars,a a, which are connected to each other at their outer ends by a spiral spring, b.- Between these ratchet-bars passes a transverse shaft, F, which is provided with a fly-wheel and a driving-pulley, and at a point opposite these ratchet-bars with aratchet-wheel, G, having side flanges, c c.

The shaft and operating parts of the hereinbefore-described apparatus are secured within suitable journals to the frame.

It will be noticed that the-ratehet-bars here inbei'ore described are provided with teeth which incline in opposite directions, which .will engage with the ratchet-teeth on the wheel G and cause the same to rotate one of the ratchet-bars engaging wit-h the ratchet-teeth, while the other slips over or under the same, thus causing the shaft to which the ratchetwheel is attached to rotate when the ratchetbars are reciprocated. It will be also noticed that the side flanges, c, serve to hold these ratchet-bars in place.

The operation of this invention is as follows: \Vhen the lever D is reciproeated, by means of hand-poweir or otherwise, .the pendulum lever C is caused to reciprocate, the weight above and below the same increasing thepower, as it is only necessary for us to throw the same off a vertical line, when gravity will assist the motion of the pendulum. pendulum is oscillated, motion is communicated to the shaft B and from thence to the ratchet-bars, where it is converted by the means hereinbefore described into a rotary motion. I

YVe are aware that prior to our invention de vices for converting motion have been con structed in which weighted pawls with ratchet teeth attached to a weighted pendulum are shown, as in Patent No. 1%,599, and we do 0 not claim such. Our invention may be considered an improvement thereon;

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

In an apparatus for converting a recipro eating into a rotary motion, the pendulumrod G provided with weights at each end, and

hen this 80 v means for giving an impulse to the same, the In testimony whereof we affix our signatures transverse bar B, with projecting arm E, and in presence of two witnesses. pivoted ratchet-bars united at their ends by a ALEXANDER ELSON. spring, b, in combination witha ratchet-wheel, F.
